TB67S105FTG,EL

Overview

The TB67S105FTG,EL is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It features a 48-pin WQFN package with exposed pad for surface mount installation. The device supports a load voltage range of 10 V to 40 V and delivers an output current of 1 A per phase. It operates on a supply voltage between 4.75 V and 5.25 V with a quiescent current of 2.5 mA. The component functions within a temperature range of -20°C to +85°C and includes four output channels configured as half-bridges.

Feature Summary

• Integrates control logic and power MOSFETs into a single fully integrated driver solution
• Supports parallel interface for straightforward digital control connections
• Includes built-in protection mechanisms against overcurrent and thermal overload

Applications

• Industrial automation equipment requiring precise motion control
• Office automation devices such as printers and scanners
• General purpose bipolar stepper motor drive circuits

Procurement Notes

Verify the complete part number including the EL suffix to ensure correct tape and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for any specific ordering suffixes that may indicate different packaging or material compositions. Ensure compatibility with existing PCB footprint designs utilizing the 48-WQFN package dimensions.

Selection Notes

Select this component when driving bipolar stepper motors with moderate current requirements up to 1 A. The low quiescent current makes it suitable for applications where standby power consumption is critical. The wide operating temperature range supports deployment in varied environmental conditions. Consider thermal management solutions given the power dissipation characteristics of the WQFN package.

Part Context

This driver belongs to Toshiba's TB67S series of stepping motor controllers designed for compact industrial and office automation applications. The series offers various current ratings and voltage capabilities to suit different motor specifications. The TB67S105 variant specifically targets lower power bipolar stepper motors while maintaining high reliability and integration density.

Replacement Considerations

Consult official Toshiba documentation for verified substitute part numbers within the same product family. Cross-reference pinouts and electrical parameters carefully when considering alternative drivers from other manufacturers.
